BackgroundDelayed puberty (DP) affects approximately 2% of adolescents. In most patients of both genders, delayed puberty is due to constitutional delay in growth and puberty (CDGP); it is a self-limiting condition starting later than usual during puberty but progressing normally. Other causes of DP include permanent hypogonadotropic hypogonadism, functional hypogonadotropic hypogonadism, and gonadal insufficiency.MethodsNine patients admitted to the Ankara Atatürk Sanatoryum Training and Research Hospital Pediatric Endocrinology Department with hypogonadotropic hypogonadism between January 2012 and December 2022 were analyzed.ResultsNine patients who applied to our pediatric endocrinology clinic with delayed puberty were analyzed. These nine patients were diagnosed and reported as hypogonadotropic hypogonadism with molecular methods. We aimed to determine the status of these cases from a molecular point of view, to emphasize the importance of hypogonadotropic hypogonadism in patients with delayed puberty, and to reveal the rarely encountered delayed puberty together with the clinical and laboratory data set of the patients.ConclusionsTo emphasize the importance of hypogonadotropic hypogonadism, which is a rare cause of delayed puberty, the molecular predispositions of our patients followed in our clinic are reviewed, and the data we have provided will contribute to the accumulation of data in this area.
